How to Import Outlook Emails to Gmail (Step-by-Step)

You're switching from Outlook to Gmail. Maybe your company moved to Google Workspace, maybe you're done paying for Microsoft 365, or maybe you just want your email in one place. Whatever the reason, you need your old emails in Gmail.

The bad news: there's no "Import from Outlook" button in Gmail. The good news: there are several methods that work, and at least one of them is free and doesn't require any third-party software.

Here are four ways to import Outlook emails to Gmail, ranked from simplest to most involved.

Method 1: Gmail's built-in IMAP import (recommended)

Gmail has a built-in tool that connects to any email provider over IMAP and copies your messages. It works with Outlook.com (Hotmail), Exchange Online, and any IMAP-enabled email server.

Gmail will begin pulling emails from Outlook in the background. You can close the browser — the import continues on Google's servers. Imported emails get a label matching your Outlook email address, so they're easy to find.

Limitations:

• Only imports the last 30 days of email by default (you can change this in import settings, but very old emails may not transfer)
• Doesn't import Outlook folders as Gmail labels reliably — some folder structures get flattened
• Can be slow for large mailboxes (5GB+ may take several days)
• Doesn't work if your Outlook account has two-factor authentication without an app password — you'll need to generate one in your Microsoft account security settings

Troubleshooting: "Can't connect to your other email"

This is the most common error. Usually it means one of three things:

1. Two-factor auth is blocking it. Go to your Microsoft account > Security > App passwords, and generate a password specifically for the Gmail import.
2. IMAP is disabled. In Outlook.com, go to Settings > Mail > Sync email, and make sure "Let devices and apps use IMAP" is turned on.
3. Your organization blocks IMAP. If this is a work Exchange account, your IT admin may have disabled IMAP access. You'll need to ask them to enable it or use the Google Workspace migration tool instead.

Method 2: Google Workspace Data Migration Service

If you're a Google Workspace admin migrating a team from Exchange or Microsoft 365, Google has a dedicated migration tool built into the Admin Console.

This tool is significantly faster than Gmail's personal import. It handles large mailboxes better, preserves folder-to-label mapping more accurately, and lets you migrate multiple users in parallel. It also supports PST file uploads for offline migrations.

Catch: This is only available to Google Workspace admins. If you're on a free Gmail account, you can't use it.

Method 3: Thunderbird as a bridge (PST file method)

If you have a PST file (Outlook's export format) but no active Outlook account, you can use Mozilla Thunderbird as a free intermediary to get those emails into Gmail.

This method gives you the most control. You can selectively move folders, clean up duplicates before uploading, and preview emails before they hit Gmail. The downside is that it's entirely manual and can be slow for large archives — Thunderbird's IMAP sync isn't optimized for bulk transfers.

Important: If your PST file is over 2GB, Thunderbird may struggle. Split large PST files using Microsoft's ScanPST.exe tool (included with Outlook) before importing.

Method 4: Outlook desktop + Gmail IMAP

If you still have the Outlook desktop app, you can add your Gmail account as an IMAP account inside Outlook, then drag emails from your Outlook folders to the Gmail folders.

This method is intuitive if you're already comfortable with Outlook. You can see exactly what's moving where. The limitation is speed — dragging thousands of emails is slow, and Outlook sometimes disconnects during large transfers. Do it in batches of 500–1,000 emails at a time.

Comparison: which method should you use?

Method	Best for	PST support	Preserves folders	Speed	Cost
Gmail IMAP import	Personal, simple	No	Partial	1–2 days	Free
Google Workspace migration	Business, bulk	Yes	Yes	Hours–days	Free (admin only)
Thunderbird bridge	PST files, no Outlook	Yes	Manual	Hours (manual)	Free
Outlook drag-and-drop	Selective migration	Yes (open in Outlook)	Manual	Hours (manual)	Free (needs Outlook)

Our recommendation: If you're migrating a personal account, start with Method 1 (Gmail's built-in import). It's the easiest and handles most cases. If you're a Workspace admin, Method 2 is purpose-built for you. Only use Methods 3 or 4 if you need to import a PST file or want granular control over which emails move.

What you lose when switching from Outlook to Gmail

The emails will transfer fine. It's the workflow that changes. Here's what catches most people off guard:

• Conversation threading. Gmail groups related emails into threads by default. Outlook shows each message separately. If you hate threaded view, you can disable Gmail's conversation view, but you lose some functionality.
• Per-message sorting. In Outlook, you can sort your inbox by sender, date, size, or subject with one click. Gmail's web interface doesn't support column-based sorting. Everything is sorted by date, always.
• Offline access. Outlook works offline by default. Gmail requires a browser and internet connection (Gmail Offline exists but is limited). You need a desktop app for proper offline Gmail.
• Rules vs. filters. Outlook Rules are more powerful than Gmail Filters. Gmail filters can't move emails between labels conditionally or trigger multi-step actions the way Outlook rules can.
• Desktop notifications. Outlook's desktop notifications are native and reliable. Gmail's browser notifications are inconsistent and disappear when you close the tab. See our guide on fixing Gmail desktop notifications.
• Email templates. Outlook has native templates that are easy to create and use. Gmail has "Templates" (formerly Canned Responses) but they're buried in settings and clunky to manage. Read more in our Gmail templates guide.

Most people who switch from Outlook to Gmail don't miss the email itself. They miss the desktop client experience: sorting, offline access, templates, and not having to live in a browser tab.

Getting the Outlook experience in Gmail

If you've switched to Gmail but miss how Outlook worked, you don't have to go back. A desktop email client for Gmail can restore most of what you lost:

• Per-message sorting — sort by sender, date, subject, or size
• Non-threaded view — see every email as a separate row, like Outlook
• Offline access — read and draft emails without internet
• Desktop notifications — native system notifications that don't depend on a browser tab
• Quick templates — reusable email templates with one-click insert

After the import: cleanup checklist

Once your emails are in Gmail, take 15 minutes to clean things up:

1. Check label organization. Imported Outlook folders may appear as labels with odd names. Rename or nest them under a parent label like "Outlook Archive."
2. Set up forwarding. If people still email your old Outlook address, set up auto-forwarding in Outlook.com (Settings > Mail > Forwarding) to your Gmail.
3. Update your contacts. Let key contacts know your new email address. Set up a "vacation responder" on your old Outlook account that says you've moved.
4. Import contacts separately. If you didn't import contacts during the email migration, export them from Outlook as a CSV and import into Google Contacts (contacts.google.com > Import).
5. Create Gmail filters. Recreate your most important Outlook Rules as Gmail Filters (Settings > Filters and Blocked Addresses > Create a new filter).
6. Set up a desktop client. If you relied on Outlook as a desktop app, set up a Gmail desktop client so you're not stuck in a browser tab.

FAQ

Can I import Outlook emails to Gmail for free?

Yes. Gmail's built-in IMAP import (Settings > Accounts and Import > Import mail and contacts) is free. It connects to your Outlook account and copies your messages. Google Workspace admins also have access to the free Data Migration Service for bulk imports.

Will my Outlook folder structure transfer to Gmail?

Partially. Gmail uses labels instead of folders. When you import via IMAP, Outlook folders become Gmail labels. The names usually match, but nested folders may get flattened into labels with slash separators (e.g., "Work/Projects"). You'll likely need to reorganize after the import.

How long does it take to import Outlook emails to Gmail?

For Gmail's IMAP import: 1–2 days for mailboxes under 5GB, up to a week for 10GB+. Google Workspace's migration tool is faster for large migrations. Manual methods (Thunderbird, Outlook drag-and-drop) depend on your internet speed and how many emails you're moving.

Can I import a PST file directly into Gmail?

Not into a free Gmail account. Google Workspace admins can upload PST files through the Data Migration Service. For free Gmail, you need an intermediate step: open the PST in Thunderbird or Outlook, then sync to Gmail via IMAP. See Method 3 above for step-by-step instructions.

What do I lose when switching from Outlook to Gmail?

Your emails transfer fine, but the workflow changes. The biggest losses are per-message sorting (Gmail only sorts by date), offline desktop access (Gmail lives in a browser), native templates, and Outlook-style rules. A desktop Gmail client like ChainMail can restore sorting, offline access, and templates.
